Pro-athlete Optical Illusion?

Below is what could be the first Pro-athlete optical illusion. Here we have two apparent members of teams in the National Basketball Association squaring off on the court in anticipation of a duel of titans. How was this picture produced? What lighting, special effects or camera lens could account for the seeming disparity in height? Could it be a image that was created in a software package like Photoshop?



Or could it just be that one player is in fact 5 foot 5 inches tall and the other is 7 foot 1 inch tall?
